A Perfect Match for Hard Rubber Mouthpieces Your current ligature may hold the reed in place, but might not allow it to vibrate to its fullest. To that end, Francois Louis has devised a practical solution that firmly grips the reed against your mouthpiece while maximizing its resonance capabilities. Designed for hard rubber mouthpieces, the Pure Brass Ligature holds the reed using a single pressure plate. Thanks to its uniquely designed brass resonators and rolls, it makes minimal contact with the mouthpiece. It's held together with pure brass wires, and tightens with a single top screw. Altogether, the Pure Brass Ligature allows your reed and mouthpiece to vibrate to their fullest without dampening or absorbing the sound. Our Sweetwater saxophonists absolutely love the Francois Louis Pure Brass Ligature, and recommend it to any player who wants to get more out of their setup.Francois Louis Pure Brass Ligature Features: Brass alto
